the electromagnet works

Solenoid is energized to produce a magnetic, like a magnet can be  adsorbed ferrous objects. Electromagnet can be applied to a variety of  areas, such as large amusement equipment, automotive, aerospace,  industrial, and other hopper magnet  undertakings. Common applications such as solenoid: punch the time  clock at work, the supermarket cash register, enter the number of units  of automatic doors. These electromagnets by the magnetic field energy is  converted, and then the magnetic force generated by the magnetic field  acting on the center of the electromagnet core, the core movements. The  main application is the core of the electromagnet forces generated by  movement. This can be done a few grams minimum force tens of grams, in  theory, can do infinitely large, basically able to do almost a hundred  kilograms. The Magnetic Traps  effect of the current is the current that the magnetic field around  the. The electromagnet is energized, the current through the coil  generates a magnetic field, the magnetic field generated in the core  operation
